UNDERGROUND MINES 

By Ernest J. Conway 1 and Richard L linger 2 



ABSTRACT 

This report presents engineering drawings for six material handling devices for underground coal 
mines. The devices were designed under a U.S. Bureau of Mines program to reduce injuries from 
material handling during mine and equipment maintenance. The six devices are (1) scoop-mounted lift 
boom, (2) swing-arm boom, (3) heavy-component lift-transport, (4) mine mud cart, (5) container- 
workstation vehicle, and (6) timber car. Each device is described briefly, and recommendations are 
made concerning the design of new devices.

INTRODUCTION 



Manual material handling represents a critical and per- 
sistent source of personnel injuries in underground coal 
mining operations. On an annual basis, such injuries 
represent the largest category of nonfatal, lost-time 
injuries, accounting for 35% of all lost-time injuries in 
1983 and 1984, according to U.S. Mine Safety and Health 
Administration data. Approximately 26% of all injuries 
related to manual material handling are associated with 
the performance of mine maintenance or equipment 
maintenance tasks (fig. 1). 

As part of its program to improve health and safety 
conditions in mines, the Bureau of Mines recently com- 
pleted a research program that addressed the material 
handling problems of mine maintenance and equipment 



maintenance. Under contract H0113018 with Monterey 
Technologies, Inc., a detailed analysis of mine- and 
machine-related tasks was completed and sources of 
injuries were identified. Concepts for simple material 
handling devices that could replace manual handling were 
then developed and evaluated. Six of these devices were 
fabricated and delivered to operational underground coal 
mines for testing and evaluation. 

This report presents a brief discussion of the six devices, 
along with associated engineering drawings. The report is 
intended for mine operators who wish to make use of the 
design concepts to manufacture similar devices for use in 
their mines.

after year. 



SUMMARY OF DESIGN RATIONALE 



This project specifically addressed material handling 
tasks related to mine maintenance and equipment 
maintenance performed in underground coal mines. Sur- 
face material handling tasks and the transporting of sup- 
plies or materials from the surface to the operating section 
were outside the scope of this effort. 

MINE AND EQUIPMENT MAINTENANCE 

Representative mine maintenance tasks included 

1. Installation or removal of ventilation, electrical, 
communications, or compressed-air systems. 

2. Installation of timbers, cribbing, and other 
supplemental materials used in roof or rib control. 

3. Track installation, repair, and retrieval. 

4. Rock dusting, installation of air control screens, 
electrical wiring, installation of warning or other systems. 

Typical machine maintenance tasks falling within the 
scope of this project included 

1. Removal or replacement of belt drives, heads, 
pumps, drive motors, and other major machine parts on 
stationary equipment. 

2. Assembly, installation, and repair of mine 
equipment, including mobile face equipment. 

3. Routine servicing of mining equipment. 

All underground coal mine seam heights were included 
in this study. However, emphasis was placed on mid to 
lower scam coal mines (under 58-in seam height), because 
preliminary data suggested that the highest risks of manual 
material handling injuries were to be found in those seam 
heights. The study included a review of relevant material 
handling literature and past Bureau programs, visits to six 
operating coal mines, and an extensive analysis of the 
Mine Safety and Health Administration's accident data 
base. 

The mine maintenance and equipment maintenance 
tasks investigated involved, by their very nature, the 



manual handling of supplies and equipment components. 
Individual modules of the items handled might range in 
weight from a few to several thousand pounds. Because of 
the operational constraints in underground coal mines, 
these materials and components often have to be manhan- 
dled from the supply dropoff point to the place where they 
will actually be used or installed. 

Components used in equipment maintenance are typi- 
cally hoisted onto a railroad car, scoop bucket, or main- 
tenance jeep on the surface. They are then transported to 
the section where the disabled machine is located. At that 
point, they are manually lifted off the rail car or jeep or 
ejected out of the scoop bucket and manually carried to 
the installation position. Occasionally, hoists or come- 
alongs are attached to roof bolts in order to aid in this 
process. Replaced components are then manually loaded 
into the transport vehicle for shipment to the surface. 

Mine maintenance materials (e.g., timbers, rock dust 
bags, roof bolts, etc.) are typically loaded in bales or via 
pallets onto railcars or into scoop buckets for shipment to 
or near the working section. At the end of the rail line, 
the bales or pallets are broken down for manual loading 
into scoops or onto other transport vehicles for delivery to 
work locations. (One mine visited had rubber-tire- 
equipped railcars that could be detached at the end of the 
rail line and towed by battery-powered vehicle to the work 
locations or section supply area.) Once the materials are 
dumped near the work locations, miners manually carry 
them to the maintenance point for use. These mainte- 
nance personnel may lift materials weighing 50 to 100 lb 
continually on a daily basis. They handle materials 
weighing 1,000 lb or more (sections of rail or steel arches) 
on a monthly or more frequent basis. 

Analyses of material handling injuries in the six mines 
visited indicated that 

1. 39% of all mine maintenance and 32% of all 
machine maintenance injuries involved the lower back, 

2. 45% of all mine and 39% of all machine 
maintenance accidents were the result of overexertion, and 

3. 68% of mine maintenance injuries involved the 
handling of timbers, posts, caps, and cribbing materials, 
while 32% of the machine-related accidents involved the 
handling of metal machine components. 



MECHANIZATION REQUIREMENTS 

The design implications of these and other findings 
revealed during studies of material handling tasks related 
to mine and equipment maintenance can be summarized 
by the following mechanization needs: 

1. Devices to lift or lower and rotate machine 
components weighing up to 3,000 lb, for removal from and 
replacement on mining equipment. 

2. Devices to lift or lower components of up to 500 lb 
in and out of scoops, off railcars and on or off other 
mobile vehicles. 

3. Carts or other devices to transport small quantities 
of materials weighing up to 500 lb from storage areas or 
railheads to working sections. 

4. A device to raise and support crossbeams for 
temporary roof support while permanent roof supports are 
installed. 

Six material handling devices were developed to fulfill 
these needs. Particular attention was focused on making 
the designs practical, low cost, and easily fabricated so as 



to be broadly applicable in underground operations. 
Where possible, the designs were simplified and off-the- 
shelf components used to permit fabrication of the devices 
by mine personnel on-site. 3 

The devices discussed in this report are not intended to 
be final designs. Rather, they are working prototypes that 
have been field evaluated and are presented herein in the 
hopes of stimulating other innovative designs on the part 
of mine personnel. 

The six devices include 

1. Scoop-mounted lift boom. 

2. Swing-arm boom. 

3. Heavy-component lift-transport. 

4. Mine mud car. 

5. Container-workstation vehicle. 

6. Timber car. 

Functions performed by, and design specifications for each 
of these devices are discussed in the following section. 



PROTOTYPE MATERIAL HANDLING DEVICES 



SCOOP-MOUNTED LIFT BOOM 

One of the major identified needs was for a simple 
boom device to lift and transport components weighing up 
to 3,000 lb in the underground environment. The device 
had to be mounted on a powered mobile machine and had 
to be installed and removed quickly to minimize produc- 
tion downtime for the machine. This tool would be used 
for transporting and maneuvering heavy machine compo- 
nents such as a continuous miner head. 

A quick mount-dismount lift boom device was 
developed for installation on the front of a small scoop 
with its bucket removed (figs. 2-3). 

The design features of the scoop-mounted lift boom 
include 

1. A 3,000-lb lift capacity. 

2. Manual or powered lift capability. 

3. Installation and removal in 5 min or less. 



4. Ready storage in working sections or on mobile 
machinery. 

Four attachment points secure the lift boom to the 
scoop lift mechanism by means of four pins. The pins 
correspond in size and location to the pins used to secure 
the scoop bucket. The overhead design of the lift boom 
permits lifting or lowering of components being handled. 
The bucket tilt mechanism provides up and down 
maneuvering of the components, while the scoop's normal 
steering permits lateral and forward and reverse 
maneuvering. 

Appendix A provides details on the fabrication of the 
lift boom device, including a summary of the materials and 
components needed. 

3 Specific products are identified in the appendixes as the materials 
used in fabricating the prototypes; however, comparable materials may 
also be used. Reference to specific products docs not imply endorse- 
ment by the Bureau of Mines. 




Figure 2.— Testing the scoop-mounted lift boom. 



SWING-ARM BOOM 

Accident and biomechanical analyses suggested the 
need for a simple swivel crane or boom device to lift 
components on and off transport vehicles and to assist in 
maneuvering heavy machine components in confined 
spaces. 

To address these requirements, a lightweight, 
removable, stowable lift boom was designed (figs. 4-5). 
This boom can be installed at various locations on 
maintenance carts or on mining machines themselves. The 
height of the boom can be varied by quickly changing the 
boom leg. The inexpensive mounts can be permanently 
welded at various locations on the machine frame and are 
designed to resist damage during normal machine 
operation. Two or more quick mounts can be installed on 
the same machine to permit access to all machine 
locations. 

Design features of the swing-arm boom include 

1. Load capacity of 500 lb. 

2. Boom height range from 24 to 68 in, depending on 
leg length. 

3. Arm radius of 24 to 48 in. 

4. Mounting and stowing without tools. 

5. Light weight for carrying by one person.

Appendix B provides detailed drawings of the boom and 
the materials required for its fabrication. Several commer- 
cially available swing-arm cranes could be readily adapted 
for the same purpose. 

HEAVY-COMPONENT LIFT-TRANSPORT 

Another identified need was for a floor-type main- 
tenance jack that could be used to lift heavy machine 
components from the bottom, transport them over short 
distances, and lift them into position for installation. 
Saddles on the lift point could be designed to permit 
additional maneuvering of the component during actual 
installation. This type of device could be used, for 



example, to install drive motors under the nonremovable 
fenders in shuttle cars. 

This prototype is shown in figures 6 and 7. The device 
utilizes a standard hydraulic floor jack to provide the lift 
mechanism. The jackhead itself is tillable and rotatable to 
permit close-in maneuvering. The jack mechanism travels 
along the device frame by means of a sump drive mech- 
anism. This motion permits forward-backward movement 
of handled components and balancing of components over 
the lift-transport device wheels during travel. The long 
handle permits the user leverage by which to maneuver 
loads up and down or sideways, as required. Dual tires or 
oversized balloon tires increase the device's stability and 
permit easy movement over uneven floors. 




Figure 5.— Boom being mounted in removable base. 

The design features of the heavy-component lift- 
transport include 

1. Up to 1,000 lb lift capacity. 

2. Balloon tires for ease of transporting manually. 

3. A standard automotive floor jack for the lift 
mechanism. 

4. Ability to lift and maneuver a heavy component as 
it is being removed or replaced on a mining machine. 

5. Jackhcad that can be trammed forward or back on 
the frame for close-in maneuvering or for load balancing. 



Appendix C presents detailed drawings of the lift- 
transport mechanism and lists materials and components 
required for its fabrication. Note that single balloon tires 
could be substituted for the tandem tires illustrated in 
these drawings. 

MINE MUD CART 

One of the basic problems faced by all miners is that of 
moving machine components or supplies such as concrete 
blocks from the supply storage area to the point of use. If 
a powered vehicle is not available, the task must be 
accomplished manually. The intent of this concept was to 
design a small, manually pulled cart that could transport 
up to 900 lb of materials over a short distance. 

The mine mud cart has the following design features: 

1. Narrow width to permit passage by a parked mining 
machine. 

2. Tandem design to prevent tipover if one unit is 
loaded and the second is empty. 

3. Balloon tires for transit through mud or water and 
over mine floors. 

4. Handle designed for pulling by one or two people. 

Figure 8 illustrates a tandem cart concept using eight 
wheels. The vehicle can also be fabricated as a single cart. 
Appendix D provides design details for a tandem cart with 
four wheels and its major components and materials. 

CONTAINER-WORKSTATION VEHICLE 

Tools and supplies required for many maintenance tasks 
performed in a section can be mounted on a transportable 
container. This concept is for a device that allows a single, 
manually powered mechanism to lift and transport such 
containers (figs. 9-10). There are many uses for the 
containers themselves, such as tool station, lubrication 
module, rock dust unit, fire and safety equipment storage, 
repair workstation, cable-splicing module, etc. 

To move the container around the working section, the 
transporter is positioned around the container and a lift 
mechanism raises it off the floor and positions the load 
slightly ahead of the axle. The load is carried by the 
wheels while the operator controls motion by pulling, 
steering, and balancing the unit on its axle.

Figure 8.— Mine mud cart. 



Design features of the container-workstation include 

1. Rapidly interchangeable containers that can be 
picked up or dropped off as required. 

2. Containers that can be used as secured storage units 
when dismounted from the vehicle. 

3. Up to 1,000-lb load capacity. 

4. Adjustable ground clearance. 

5. Balloon-type tires for easy transporting on 
unimproved mine floor. 

6. A towbar that can be adapted for towing behind 
utility vehicles. 

Detailed drawings and a list of materials and 
components for the device are provided in appendix E. 



TIMBER CAR 

One of the most hazardous material handling tasks in 
underground mining is that of installing crossbeams for 
roof support. A need was identified for a mechanism to 
lift beams weighing up to 500 lb to the roof, where they 
could be held in place until permanent supports could be 
installed (figs. 11-12). The device shown utilizes a 
modified hydraulic floor jack to provide the lift. The jack 
mechanism is moved manually along a track down the 
center of the car. This forward-backward movement 
permits easy positioning of the load. In addition, the 
jackhead rotates to ease positioning of extra-long 
members. 

Design features of the timber car include 

1. Up to 500-lb lift capacity with a 60-in lift height 
(suitable for low- to medium-seam mines).

double duty as a 40-ton-capacity supply car. 

3. A modified automotive floor jack for the lift 
mechanism. 

4. Jack that can be maneuvered forward or back in its 
track for close-in maneuvering. 



Appendix F presents detailed drawings of the track and 
jack assemblies for the timber car. Note that the 
components could be mounted on any suitable flatcar 
rather than be built as part of the car. 



CONCLUSIONS AND RECOMMENDATIONS 



On-site visits, task analyses, and interviews suggest that 
the majority of the risk exposure associated with material 
handling in underground coal mines results from the lack 
of properly designed and easily accessible material 
handling tools, devices, and vehicles. Mine personnel tra- 
ditionally rely on a "couple of extra hands" or on crowbars, 
come-alongs, and other makeshift tools to manhandle even 
the largest components of mining machinery. Similarly, 
lacking appropriate tools, carts, and other handling devices, 
mine personnel manually move timbers, posts, beams, and 
other heavy materials on a continual basis. In most 
instances, tools are simply not available for these heavy 
lifting, transporting, and positioning tasks. 

These investigations also revealed that what is needed 
is not another complex, powered vehicle designed to per- 
form any and all maintenance jobs. Rather, what is 
required is a series of simple, task-specific tools, aids, and 
devices to be housed and used in the working sections and 
maintenance areas. Mine personnel tend not to wait 30 to 
60 min while a special vehicle or tool is brought in from 
another area of the mine. The material handling hardware 
should be relatively easy to fabricate and should, where 
possible, utilize off-the-shelf components. It should be 
relatively inexpensive and designed for fabrication in mine 
shops. The prototypes of six such devices that were devel- 
oped and tested by the Bureau are described in this report. 

There appears to be a sincere interest on the part of 
mine management and safety and production personnel in 
reducing injuries related to material handling. There is 
also a need for exposure to new ideas, products, and 
material handling mechanization concepts to assist mine 
personnel in identifying their own unique handling require- 
ments and in coming up with appropriate mechanical solu- 
tions to these problems. The concepts presented here 
were designed to stimulate the development of other 
mechanization concepts to address mine-specific material 
handling problems. 

Three major recommendations are suggested with 
respect to development of material handling devices: 

1. Systems Approach to Material Handling . Many 
larger mines have developed so-called systems for moving 
huge quantities of supplies and materials from surface 
storage areas to in-mine drop points or supply depots. 
These systems, however, have many missing elements and 



built-in problems. For example, pallets are utilized to load 
quantities of 90-lb cement blocks or 100-lb bags of rock 
dust from the storage onto the supply train. Forklifts or 
hoists may be used to offload the pallets at the dropoff 
points. However, personnel must manually load these 
supplies onto battery-powered vehicles or physically lug 
them to the point of use. This systems-approach thinking 
has failed to account for the fact that the blocks still weigh 
90 lb and the bags 100 lb apiece when they get into the 
mine. These loads are too heavy for personnel working in 
confined workspaces and on unimproved mine floors. If 
a systems approach is to be used, it should start with the 
end user or task and work backward from there. 

2. Task-Specific Tools . As in any industry, the design 
of special tools to perform specific tasks is often over- 
looked. In underground mining, few if any tools or devices 
have been developed to cope with specific material han- 
dling tasks. Exposure to high-risk tasks could be substan- 
tially reduced if appropriate task-specific tools were 
available. For example, the transporting of materials 
through a 3- by 3-ft man door requires the miner to lift a 
50- to 100-lb (or heavier) object, rotate his or her body, 
and heave the object through the man door opening. 
Exposure to overexertion-type injuries is very high. If a 
simple slide or materials conveyor were available, the 
miner could simply pass the material through the opening. 
Similar aids and mechanical tools are required for han- 
dling rail sections, timbers, posts, cribbing materials, etc. 

3. New Technologies . The search for new technologies 
is an ongoing process in any industry. In underground 
mining, however, it is even more important since so little 
completely new technology has been introduced to this 
sector. With respect to material handling, this search 
should focus on new, low-cost, reduced-weight materials 
for mine maintenance and safety applications. It should 
address improved designs and packaging for manual 
handling in operational environments. It should cover 
improved methods of installation and maintenance of the 
mine and the mining equipment. It should focus on ways 
of reducing mine maintenance (e.g., cleaning up along belt 
lines) and machine maintenance (e.g., autolubing systems). 
It should attempt to replace muscle power (particularly 
back muscles) with mechanical or hydraulic power.
